Thin films for solar container batteries

How do we fabricate a thin-film microbattery at low temperatures?

In this work, we creatively fabricate an all-solid-state thin-film microbattery at low temperatures by combining a sputtered thin-film iron oxysulfide (FeOS) cathode and a thin-film Si anode (Fig. 1 C). The redox medium (Li-ion) is supplemented by in situ short-circuit prelithiation technology for Si microelectrodes (Materials and Methods).

What is a transparent thin-film lithium-ion battery (LIB)?

In this work, a transparent thin-film lithium-ion battery (LIB) with IGZO as the anode is proposed as the on-chip power source. Then, TFT with IGZO as the channel layer and PD with IGZO as the photosensitive layer are also prepared. All the devices are fabricated on a single glass substrate for constructing an integrated transparent microsystem.

What is a thin-film Li-Se battery?

Here, the first successful fabrication of all-solid-state thin-film Li-Se batteries is reported, featuring an ultra-thin (≈1.4 µm) lithium phosphorus oxynitride solid electrolyte and a hybrid Se cathode supported by vertical graphene nanoarrays (VGs).

What are thin films made of?

Thin films are composed of two distinct components, namely the layer itself and the substrate onto which it is deposited. Thin films have the ability to exist as multiple layers, including but not limited to thin-film solar cells and electrochromic (EC) cells .

Is Lipon suitable for thin-film batteries?

As a case in point, despite LiPON's modest ionic conductivity of 2 × 10 −6 S cm −1, its practicality for thin-film batteries is evident due to its minimal thickness of 1 µm, resulting in an ASR of 50 Ω cm 2. In comparison, this is on par with a 500 µm thick garnet ceramic electrolyte showcasing a superior conductivity of 10−3 S cm −1 .

Are thin films suitable for chromogenic applications?

Thin films have the ability to exist as multiple layers, including but not limited to thin-film solar cells and electrochromic (EC) cells . Multilayer thin films possess favorable characteristics that render them appropriate for a wide range of technological applications, including chromogenic applications.
